A project that shows how modern administration, citizen-friendliness, and climate protection can go hand in hand: in just one and a half years of construction, the district's new four-story building was erected on the barracks site behind the train station in Kehl. With this approximately 3,500-square-meter building, the Ortenau district has consolidated its offices in Kehl. Vollack planned and implemented an open, service-oriented administrative facility that meets the high standards of modern administration, is barrier-free, and is also easily accessible by public transportation.
 

The building will meet the highest energy standards, as it is designed as a KfW Efficiency House 40. Vollack will use the thermal storage capacity of concrete for an efficient heating and cooling supply. So-called concrete core activation, in combination with a seasonal ground storage system, will reliably ensure comfortable temperatures in the building. Green energy will be produced by a photovoltaic system. Vollack also relies on regional recycled concrete. Its advantages lie in local value creation, short supply chains and the conservation of resources compared to conventional concrete.
